What is the difference between an atom and a molecule? A molecule and a crystal?
Differentiate among a molecule, an atom and a crystal.
Explanation of Solution
Write the differences among the molecule, an atom, and a crystal.
Molecule |
Atom |
Crystal |
1. A molecule is a combination of two or more atoms. |
1. An atom is the smallest particle in an element having the properties of the element in it, which means, this is the un-split-able part of an element. |
1. Crystals are formed when metals from liquid or soft state are solidified as the atoms get rearranged into different neat configurations. This is what we know as crystals. |
2. It is not visible to the naked eye, though it can be seen with the help of a high capacity magnifying microscope and some other devices. |
2. We cannot see atoms through our naked eyes. Atoms are also the basic building blocks. |
2. A crystal consists of atoms, molecules or ions ordered in a highly densed microscopic structure where those are bound together by inter atomic forces also known as chemical bonds. For example, ionic bonds, metallic bonds, Vander Waals bonds, covalent bonds and so on. |
3. Properties such as physical or chemical are depend on atoms from that they are bonded. |
3. Properties such as physical or chemical are depend only on one type of atom. |
3. In case of crystal, physical or chemical properties are depending on parent atom, molecules, ions etc. |

Draw [322] in a body centered cubic crystal. Draw (202) in a face centered cubic crystal. The planar density of (003) should be higher than that of (002) in a body centered cubic crystal. Ture___ or False____. You need to justify why to the answer.arrow_forwardAssume we have to accommodate 18 million books, each of which has 1 billion characters. If each character can be written using 100atoms, and if the bulk atoms can be used, calculate the size of an object (in nanometers) that can accommodate all the 18 million books. Assume one atom occupies a space which is 0.25 nm in sizearrow_forward
- In the cubic structure, there are mainly 3 elastic constants including C11, C11, and C44. Now, in my simulation, the value of C11 is becoming very high due to applying pressure. So far, in the simulations I've done, it's reached around 570 GPa. If more pressure is induced, it could increase further. My question is, is this increase normal?arrow_forwardCalculate how many billion years it will take to build 1 mole of a molecule with a formula of CnH2n+2 by adding 84 million atoms per second. Assume n=8 and 1 year=365 days. Use three significant figures (e.g. say 36.4 and not 36)arrow_forwardMaterials sciencearrow_forward
